So far I've ordered twice from Costco, and once from Walgreens, using google express. Both the times my order got 'canceled' with no reason specified. There's no "why?" link/button/reason either. When I went to Costco and talked to the folks there, they said they don't deliver via Google Express. And I've no idea what went wrong with the Walgreens order, and I don't feel like trying again either. Google needs to set higher standards for themselves and their business partners if they want to compete with Amazon.
